An oceanographer daims that the mean dive duration of a North Atlantic right whale is 11.3 minutes. A random sample of 35 dive durations has a mean of 12.2 minutes and a standard deviation of 2.2 minutes. At a = 0.05 is there enough evidence to reject the oceanographer's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (a) Identify the claim and state Ho and H H (Type integers or decimals. Do not round.) The claim is the hypothesis.
